Title: Kickstand on Musashi Post by Patti on Apr 2nd, 2013, 12:46pm Ok. I know this is an absolute heresy to some, however, I hate having a really nice bike that I have to lay down or always be trying to lean on something. Is there a way to put one on a Musashi? |

Title: Re: Kickstand on Musashi Post by jayg on Apr 2nd, 2013, 2:54pm No, no don't do it, Patti! Think of all that extra weight. You can always find something to lean it on. :) Does this mean you have bought that red Musashi, or are very close to doing so? |

Title: Re: Kickstand on Musashi Post by Patti on Apr 2nd, 2013, 3:35pm Yep. Its all mine. Jay, I refuse to get caught up in all that "weight weenie" stuff. Hostel Shoppe tells me that their Volae Kickstand Gizmo "might" work but I'd rather know for certain before I order one. |

Welcome to the club. You're really going to like that bike. My Musashi is my bike for life. The only Musashi owner I know that has a kickstand on his bike is Grady B. Called him and he told me he got his from Jack at RBM, Richardson. He said he thought it was a Cannondale product. It looks like this: http://www.cannondale.com/2012-eileen-2-kickstand-21898. When you get the boom set for your X-seam check to be sure there are no crank strike issues. If there is any crank strike, you might want to install a 155 mm or shorter triple. Since I installed short cranks on my Musashi, I have not gone down on the bike. Used to be a regular occurrence. |

Title: Re: Kickstand on Musashi Post by Patti on Apr 2nd, 2013, 11:24pm Thanks, gentlemen. Those both look like good options. The Cannondale style is what I am hoping will work. Must better than those traditional greenfield types. Jay, I'm not certain I'm going to have to make any changes to the boom. It seems really close to just right, right now. I have no clue what size cranks are on it. I looked but didn't locate a size anywhere. |

Title: Re: Kickstand on Musashi Post by Mizta_Nice on Apr 3rd, 2013, 6:48am I like the click stand because I can just keep it in my bag until I need it, then it just snaps open like magic. There is one other piece beside the stand, a rubber band that stays on my hand grips to hold the brake when parked. |

Patti, if your crankset is the same as that in the below photo, it's the 165 mm SRAM Rival compact crankset (50T/34T) that was standard on the Musashi. Look on the backside of the crank arms, near the threaded pedal holes, and you will see "165" stamped in the metal. The Musashi's horizontal rear stay is 32 mm in diameter and the upper stay 26 mm. The Cannondale kickstand looks exactly like the kickstand on Grady's Musashi, however, the specs for it say it is designed for flat-sided tubes up to 23 mm thick. Maybe RBM used longer screws to adapt the kickstand to Grady's bike. http://i1021.photobucket.com/albums/af339/jayg_2010/DSC00110_zpsab0cd8c4.jpg |

That looks like my second option if I cannot get an attachable one that is functional yet unobtrusive. |

Title: Re: Kickstand on Musashi Post by Patti on Apr 3rd, 2013, 1:34pm Jay, this bike has a triple front (52-42-30), with an Origin 8 crankset. I looked where I expected to find a size, but only found a code: A09145. Mike must have made some changes for her when she bought it. I'll just have to bring it by and let you look at it sometime. :-) jayg wrote:

[/quote] I have an Origin 8 crankset with "B09155" stamped on the crank arms. It has 155 mm arms. Your crankset apparently has 145 mm arms. If you have real strong legs, maybe you can live with the installed chain rings. If not, you will need to spin to get some torque, and that means you will need chainrings with reduced tooth count. My Musashi's crankset has 148 mm arms and the chainrings are: 48T/38T/24T. |

Title: Re: Kickstand on Musashi Post by JimFPU on Apr 4th, 2013, 12:35pm With all this chainring and tooth count talk, can you offer a riders simple versiion of what it all does? :o Here is GA, looks like I'm gonna be climbing A L.O.T. when I catually get back to riding (old/new house remodeling...) |

Title: Re: Kickstand on Musashi Post by rmillay on Apr 4th, 2013, 4:16pm Jim, the relation between teeth on the ring and on the cassette is related to your ability to produce power, which is dependent on the pedaling speed. Jay's reference to crank length referred to the Musashi's succeptibility to foot strike (or even crank strike) on the front wheel when turning, but crank length also affects the torque you can generate. This has been discussed before. A good reference is www.sheldonbrown.com . For instance, for hill climbing, his gear calculator will tell you what speed you can generate with different gear and wheel combinations. Patti, for example, using the 30 front/32 rear combination on her new Musashi, can spin up hills at 6.8 mph if she can maintain 90 rpm. Playing around with Sheldon's calculator is fun, using your bike's specs, and 'what if?' situations. You can see if you need different hardware (or just more time on the bike), and why some gear changes just don't seem to work well for you. |

When crank arms are shortened there is a loss of mechanical advantage. Going to lower tooth counts on the chainrings helps regain some of that lost advantage. Lower tooth count chainrings also let you ride on the smaller cogs of the cassette where the tooth counts are closer together. That way you don't bog down as much when you upshift, as you're trying to gain speed. With a 700cx28 tire and a 52T/15T gear combo, a theoretical velocity of 23 mph would be achieved at an 83 cadence. With a 48T/15T combo it would take a 90 cadence to achieve the same velocity. The general recommendation for a crankset with short crank arms is to spin it up. According to an article by Ken Mierke, titled: "Cycling Cadence and Pedaling Economy", spinning at higher cadences reduces the watts-per-pedal-stroke, and makes the workload more tolerable for the muscles. Works for me. Haven't noticed significant degradation of my performance, due to the short cranks. The main reason I went to short cranks was to stop the knee pain I was experiencing, which they did. Elimination of crank strike on my Musashi was a secondary benefit. Don't have any hip pain from going down on the bike, anymore. With your long and strong legs there would be no need for you to go to short cranks. Your best bet might be to install a mountain bike crankset (and/or mountain bike cassette), like Kenny and I did on his GRR. These cranksets have lower tooth count rings than a road bike triple has. A downside to installing one of these cranksets is you would probably spin out in the big ring, if you pedaled down steep hills, instead of coasting. Kenny's crankset didn't cost over $40 and the bottom bracket not over $30. |
